Integuments of ovules harden as tough protective seed coats, the microphyte remains as a small bore in seed coat, this facilitates
Entry of oxygen into seed only during germination

Entry of oxygen and water into seed during germination
Entry of oxygen and water is not permittable into seed
As we have learned
seed coat -
Integuments of ovules harden as tough protective seed coats. The micropyle remains as a small pore in the seed coat. This facilitates entry of oxygen and water into the seed during germination.
